As far i know the updates into the loader are fully concentrated on GC games so it's not worthy to upgrade if you have (like me) no interest in that matter. I also stopped at v70 final.
Kirby return to dreamland isn't a problem game as far as i know, it runs fine on cIOS d2x r7 base IOS56 or d2x 8. Just install that to slot 249 and it should work perfectly.
I finished that game about two weeks ago on cfg 70. More likely you have a bad dump.
Ogg files and mp3 files stutter all the time also when i change through games wiiflow completely hangs hard reset on the wii is only possibility to get out. My wii is a 4.1E with d2x7 final. Wiiflow version is r418
I haven't played my Switch n a month or so, just been playing Xbox, and just picked to play lil and Damn that A and B, X and Y being reversed always gets me.
